Learn to live with
Practical, honest guides for city residents navigating composting, recycling bins, PSZOK centres, and smarter shopping at Polish supermarkets.
What Masiyo is
Zero-waste knowledge built for Polish cities
Warsaw, Wrocław, Kraków, Poznań. Each city has its own collection schedules, its own PSZOK network, its own quirks. Generic sustainability advice rarely fits. Masiyo exists to close that gap. We write specifically about what works in a Polish blok, with Polish supermarkets, and within Polish municipal systems.
No products are sold here. No affiliate links. Just carefully researched editorial content that you can read, bookmark, and use.
What you will find here
Four areas we cover in depth
Balcony composting
Step-by-step guides on setting up a worm bin or bokashi system on a blok balcony. What to add, what to avoid, how to manage odour in a small space.
The five-colour bin system
Poland uses five bin colours and the rules are not always obvious. We explain exactly which items go where, with practical examples from everyday Polish households.
PSZOK explained
Punkt Selektywnej Zbiórki Odpadów Komunalnych. We explain what they accept, how to find yours, and what to bring when you go.
Smarter supermarket shopping
How to reduce food waste when shopping at Biedronka and Lidl. Reading labels, planning portions, and finding refillable packaging from Polish producers.
Why Masiyo
Four things that shape how we work
Polish context only
Every guide is written around Polish regulations, Polish municipalities, and Polish shops. No generic European advice that does not apply here.
Editorial independence
No sponsored content, no affiliate income, no product sales. Our editorial decisions are guided by reader usefulness, not commercial relationships.
Urban realism
We write for people in apartments, not houses with gardens. A blok balcony is the starting point, not an afterthought.
Verified information
We check municipal regulations and producer claims before publishing. When rules change, we update our content. Accuracy matters to us.

Polish producers
Refillable packaging in Poland
A growing number of Polish producers now offer products in packaging designed to be refilled rather than thrown away. Finding them takes some research. We have done that research.
From cleaning products to personal care, our guide maps out which Polish brands offer refill options, where to find their products, and how the refill process actually works in practice.
